The #7 player was the never-heralded Billy Meyer, who had the distinction of playing mostly in the minor leagues, but when he was in the majors played for one of the worst teams ever, the 1916 A's who won 36 games and lost 117; then years later he would manage the Pirates to a 42-112 record in 1952.  Still, he was so beloved in Pittsburgh, they retired his number (1), the seventh number of all time so retired..
